Electrical switch 2P Jung 104.28 — 2-pole, 250 V, 10 A

Jung 104.28 is a 2-pole electrical switch insert designed for AC installations with a rated voltage of 250 V and a nominal current of 10 A. This switch provides simultaneous on/off control of two poles and is intended for residential and light commercial electrical circuits. The insert features protection against dismounting and is designed for screw fixing only (without claws), making it suitable for installation in compatible switch frames and flush-mounted boxes.

Advantages

The switch insert offers coordinated two-pole switching for safe disconnection of both conductors in single-phase circuits up to 10 A. Its protection against dismounting increases mechanical security after installation, and screw-only fixation ensures a stable and vibration-resistant connection in the mounting frame. The compact insert format allows integration into standard modular wiring systems and maintains compatibility with Jung frames and covers where specified.

Suitable for

• On/off control of lighting circuits in apartments and houses
• Switching small appliances and loads up to 10 A
• Two-pole isolation where simultaneous disconnection of live and neutral is required
• Retrofit or new installations using compatible modular frames

Key specifications

• Poles: 2-pole (2P) switching
• Rated voltage: 250 V AC
• Rated current: 10 A
• Mounting: screw fixing only (no claws)
• Protection feature: protection against dismounting
• Form factor: insert for modular switch frames

How to use

Install the Jung 104.28 insert into a compatible frame or flush-mounted box following local electrical regulations. Ensure power is isolated before wiring. Connect incoming and outgoing conductors to the appropriate terminals, observing polarity and secure terminal screws to manufacturer-specified torque. After wiring, fix the insert with screws into the mounting frame; claws are not used. Fit the decorative cover or rocker according to the frame system instructions. Restore power and test the switch operation to confirm reliable on/off control of both poles.

Recommendations

Use this 2-pole switch insert for circuits where both conductors must be switched simultaneously and keep the load within the 10 A rating. For installations in damp or outdoor locations, select appropriate IP-rated enclosures and follow local codes. When replacing existing modules, verify mechanical compatibility with the target frame and check that screw-only mounting is supported.
